UX Lead (Product & Growth)

About the role

Ruby Labs is a leading tech company that creates and operates innovative consumer products. We offer a diverse range of opportunities across the health, education, and entertainment industries. Our innovative teams are driving the future of consumer-led products, and we're always looking for passionate individuals to join us. Learn more about our story at: https://rubylabs.com/about-us/ We're building and scaling a high-growth D2C product used by hundreds of thousands of customers globally, and we're now entering a phase where UX is a core growth lever. We're adding new capabilities, expanding the product, and focused on improving retention, activation, and funnel performance - and we need a UX leader who can drive that. We're looking for a UX Lead who is deeply technical, data-fluent, and design-strong . You'll own UX strategy, design quality, and the research practice - not as a support function, but as a core driver of product and business performance . Today, design is mostly engineered directly in the frontend, and UX research lacks structure and direction. You will change that. This is not a 9-5 role. It's a high-ownership, high-impact position for someone who wants to build systems, lead people, and directly influence growth metrics.

Responsibilities

• UX Strategy & Growth Impact
• Take full ownership of UX, design quality, and user journeys across the product.
• Turn UX into a measurable growth lever - directly improving activation, retention, and conversion.
• Work closely with Product and Growth to design and optimize funnels, onboarding, paywalls, and retention loops .
• Audit and continuously improve the end-to-end user journey - from acquisition through long-term retention.
• Data & Analytics (Core Strength)
• Analyze product analytics independently - Mixpanel funnels, cohort analysis, retention curves, drop-off patterns.
• Connect UX decisions directly to business metrics - activation rate, retention curves, LTV, conversion.
• Define hypotheses, experiments, and success metrics for every UX initiative.
• Use session recordings (Clarity, FullStory, Hotjar) , heatmaps, and behavioral data to identify friction points.
• Proactively request and define new analytics instrumentation and reporting needs with the data team.
• Validate UX changes through A/B testing (GrowthBook or similar) - hypothesis, implementation, result analysis.
• Design Leadership
• Define, enforce, and evolve a clear, scalable design system (implemented directly in frontend, not Figma-first).
• Lead and direct designers and frontend engineers involved in UI/UX work - set the definition of done.
• Set the visual and interaction quality bar across the product.
• UX Research
• Establish a structured research practice - define priorities, run interviews, surveys, and usability tests.
• Translate raw research into prioritized, actionable product decisions.
• Direct and level up the existing UX researcher on the team - provide structure, frameworks, and clear priorities.

Requirements

• Core Strengths (Must Have)
• Data & Analytics
• Strong, hands-on ability to analyze product data independently - you pull your own funnels, you don't wait for reports.
• Deep experience with Mixpanel, GA4, Amplitude, or similar product analytics tools .
• Ability to read cohort and retention data, identify patterns, and build hypotheses from raw numbers.
• Experience designing and running A/B tests (GrowthBook, Optimizely, or similar) end-to-end.
• Retention & Growth Expertise
• Demonstrated experience driving measurable improvements in retention, activation, or LTV .
• Strong understanding of conversion funnels, retention loops, and user behavior at scale .
• Background in CRO (conversion rate optimization) or growth-driven design.
• Design Leadership
• Strong design background with a portfolio of conversion-oriented, data-validated work.
• Experience leading or managing designers - you've set direction, reviewed work, and raised team quality.
• Ability to define and maintain a consistent, high-quality design system.
• Comfortable working in environments where design is implemented directly in frontend (no Figma-first culture).
• UX Research
• Proven ability to collect both qualitative and quantitative user insights.
• Experience designing and running user interviews, surveys, and research frameworks.
• Ability to translate research into clear, actionable product decisions.
• Experience & Mindset
• 5-8+ years in UX, Product Design, or design leadership, ideally in D2C, SaaS, or consumer digital products .
• Experience working in fast-paced, growth-oriented environments with daily or near-daily releases.
• Systems thinker - designs scalable patterns, not one-off screens.
• Clear communicator - explains the why behind every design decision with data.
• Strong ownership mindset - owns outcomes, not output.
• Experience in LegalTech, document tools, or utility products .
• Familiarity with TailwindCSS, React/Next.js component implementations - you can review fronte
